nGimat Co. announced today the recent issuances of a U.S. patent and a Canadian patent directed to thin films (i.e. films 10 microns thick and less), laminates of thin films, and methods of producing thin films. Thin films and thin film laminates produced in accordance with these patents have a wide variety of technical applications including corrosion-resistance, moisture barriers, gas barriers, and protective coatings for electronic and ceramic components.
U.S. Patent No. 6,939,576, entitled "Polymer Coatings", is directed to methods of producing thin film polymer coatings from solutions or dispersions of polymeric resins. A fluid containing the polymer is applied as finely atomized droplets to a surface to form a fluid film. Concurrently, a flame is applied to the fluid film to drive off any water or solvent and to fuse and/or cure the polymer to form the thin film coating. The methods of this patent are suitable for applying a wide variety of polymers, both thermoplastic and thermoset. One important application of this technology is the coating of plastic beverage bottles to substantially enhance gas barrier properties. Thin films of uniform high quality are deposited in an environmentally friendly and cost efficient manner.
Canadian Patent No. 2,296,505, entitled "Corrosion-Resistant Multilayer Coatings", is directed to unique laminates of inorganic thin films. These thin film laminates are used to provide a moisture barrier and corrosion-resistance to metal substrates. The thin films of the laminates are primarily a variety of metal oxides and metal phosphates. The deposition methods taught in this patent produce films that, while very thin, are extremely durable and well-bonded to the substrates. The thinness of the films results in protected substrates having dimensions substantially unaltered from their pre-coated states, and in many cases, appearance substantially unaltered. There are already two U.S. Patents (Nos. 6,214,473 and 6,416,870) in place that protect nGimat's coatings and associated process technology.
With these new patents, nGimat has a portfolio of 36 U.S. patents, 47 non-U.S. patents and is prosecuting over 125 patent applications.
nGimat Co. is a cost-effective manufacturer and innovator of engineered nanomaterials in the following areas: nanopowders, thin films and devices. nGimat's Combustion Chemical Vapor Deposition (CCVD) and NanoSpraySM Processes along with its Nanomiser® Device enable synthesis of nanoparticles and thin films.
